Bowers & Wilkins P7 - over the ear headphones - Page 45

post #661 of 1111

anyone tried equing the P7? As I really like the accudio app (the Koss Porta Pro sounds terrific with it) I just did a custom eq in it for the P7. unfortunately there is no official one yet. The app doesn't seem to be updated often. I am an absolute beginner in equalizers, so if anything I did seems dumb it might be just for the reason that it is dumb. I took those measurements as a starting point:

http://stereos.about.com/od/StereoHeadphoneReviews/ss/Bandw-P7-Measurements.htm

 

I compared them to the measurements from the HP50 and tried to copy the frequency curve a little :) Here is what I did in detail:

 

50 hz: +1db

100 hz: +1db

200 hz: +1db

500 hz: +1db

2300 hz: -2db

7000 hz: -2db

12800 hz: +1db

14000 hz: +1db

 

so far I like what I hear. the sound is weightier and so far I didn't encounter spikes in the highs. could be just placebo I guess and I am pretty sure there is a lot of room for improvements. If anyone has something to share I would be happy to test out.

It's been awhile since I've broken-in a pair of headphones. It's a fascinating experience. I've been doing most of my A/B with a the DT1350s. Originally, as I commented in some earlier posts, the P7s seemed "harsher" then the 1350s. This morning, the 1350s sound harsher than the P7s! As perceptions change, I should probably not jump on here too hastily (he said, as he jumped on here hastily again); since these perceived fluctuations render my previous posts questionable. LOL. Having said that, the primary picture I'm getting is that the main difference between the 1350 and the P7 is sound stage (to be expected, since the 1350s are tiny). The FR (to my ears) is fairly similar. That's a good thing, since I was hoping for a comparable audio experience with a different physical fit. So, to me, the P7s are like roomier 1350s. And in just about every case, I prefer the P7 SQ (sometimes just slightly) over the 1350s.

 

Sappy, I've tried quite a bit of EQ on these. Interestingly, I keep coming back to using them with no EQ (another reversal from one of my previous posts!).

I've been discussing in the HD700 thread, a headphone I used to have. Now that I think about it, I think the P7 and HD700 has a similar signature. This is all from memory so anyone with both, please comment. A quick frequency response graph search for both seems to support this assertion.

InnerFidelity review is up, seems we agree that these are better than your typical portable headphone in scalability with better sources and amps.

Today I've found that if I use EQ to reduce the 4k area while increasing the 12-14k area, it makes the P7 less "cuppy" sounding. On many recordings these sound fine w/ no EQ, but I noticed this cuppy sound on some older recordings. I promptly made a P7 preset using the Denon headphone app. I was on the verge of getting rid of these; might keep them now...

Great review. But Momentum more neutral? Kind of lost its credibility there I think...

Haha. Well, in the end it's just one guy's opinion.

post #668 of 1111
I actually agree that the Momentum is a more neutral headphone as I stated earlier in this thread. The InnerFidelity review summarizes exactly how I think the P7 sounds, they key difference being that I actually LIKE that sound and am willing to give up some midrange to get the detailed sound and great imaging and soundstage.

I also think the measurements are a good indication of the shape of their sound. They don't account for imaging and soundstage obviously, but otherwise the P7 sounds the way it measures.

I see that review as further validation of my own opinion on these

That's what I hear...it's what the measurements show.

They look pretty damned different to me.

I didn't have those. Just did a Google image search. I think what reminded me of the HD700 was the bass.

Hmmm. Very interesting review, Tyll. Thanks for the technical data. My main issue with the P7s in a sometimes unpleasant intensity in the "uppers". I did a little EQ, as I mentioned previously, and found that if I pull down the slider in the 4kHz area it reduces this effect. According to the review, the new design of the "second cavity" affects this same area of the spectrum ("3kHz and 7kHz"). Could it be that this great new innovation is what's hurting my ears?!

Thank you Tyll for the great review. I am reassured as the sound you described is consistent with what I have heard. We may have difference preference of sound but I am very glad that I am hearing what you are hearing, and I love what I've heard. Not neutruel, but lovely colored.

Thanks.

Correct me if I'm wrong, but I actually see a more rolled-off treble on the Momentum than the P7 on your measurements. My ear also tells me the Momentum has a very audible upper bass bloom which tends to thicken the sound. I hear no such thing on the P7, not in a way that's bothering at least. I'm surprised to see that the 30hz square waves look better on the Momentum, as the P7 clearly has a tighter and more robust bass. 

 

But hey that's just me.

It is, overall. The P7 has a 'three-humped camel' kind of response. A fun response, but not a natural one. "Boxy" and "cuppy" have been used as descriptors and rightly so.
